4 HEATING APPARATUS.

Application filed April 11, 1921.

To all whomz'f nm-y canoe m:

Be it known that l, FRANK ll. LoNoAoun, a citizen of the United States, residing at Macon, in the county of Macon and State of have invented certain new and useful Improvements in :1 Heating Apparatus, of which the following is a specification.

This invention relates to air heating apparatus, and has for one of its objects to provide a device of this character having means whereby cold air is drawn downwardly from one part of a room and heated and forced upwardly atanother part of the room.

Another object of the invention is to proof this character having means whereby cold air is drawn downwardly from one side of a room, passed over a body of water to moisten the air, and heated and forced upwardly into another part of the room.

Another object of the invention is to provide a device of this character having means whereby filtered air is provided in living apartments, warm air being furnished in cold weather and cold air in warm weather with the same apparatus, and without materially changing the apparatus.

With these and other objects in view the invention consists of certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention.

The figure is a sectional elevation of the improved apparatus.

The improved apparatus comprises in general a shell or casing 10, preferably encased in-an envelope ofasbestos or other heat insulating material and indicated at 11.

The shell 10 with its envelope 11 are suspended beneath a floor represented conventionallyat 12, and with a perforated-register device 13 of suitable construction providing communication between the shell and the room or other space above the floor.

In the referred construction an air intake trunl r 14 is employed and located at any convenient point beneath the floor 12 and communicates with the room above the floor through a register 15.

Serial No. 480,530.

At its lower end the trunk 14 communicateswith a closed tank or chamber device 16 for a body of water represented at 17.

The tank or chamber is provided with means represented at 18 for supplying the tank, the supply means provided with a suitable controlling valve 15). The tank is also provided with a draw off 20 and a water gage represented at 21, to enable the stag of water in the tank to be determined.

Disposed within the lower part of the shell is a transverse perforated partition 22, and leading from the upper part of the tank 16 is a relatively large conductor 23 discharging into the shell 10 beneath the partition 22.

By this means the air passing down through the trunk 14 is carried over the body of water 17, and thereby moistened before entering the shell 10.

Mounted on the partition 22 is an open rack or frame 24 to support a heating a pliance, preferably an electric heater, inicated conventionally at 25.

Supported by the partition 22 beneath the rack or frame 24 is a fan device 26 referably operative by an electric motor indicated conventionally at 27.

The motor 27 may be arranged to use either direct or alternating current. and

may be arranged in any suitable manner, and will be of suitable size and power to operate a fan of any size or capacity, depending on the size of the room into which the air is to he forced.

The motor and the current for the heater 25 are adapted to be controlled by a suitable switch device indicated conventionally at 28 which may be located at any convenient point on one of the walls of the room.

By this simple arrangement it will be obvious that when the fan device is operated the air will be drawn downwardly through the trunk 14 and laterally through the tank 16 in contact with the water therein, thus absorbing a portion of the same, and passing thence through the conductor 23 and into the shell 10 below the heater and thence through the apertures in the member 22 and around the heater 25 by which the air is highly heated. and thence into the room through the register 12.

The air is thus forcibly and constantly cireulated through forth in the entire area of the room and the cool and heated air uniformly commingled and maintained at a uniform temerature. I

The platform or partition 22 on which thef cage 24 of the heater 25 Qrests, may be constructed of anysizeof' shape to renderkall the working parts easily accessible. By cutting out the electric-heater'aiid operating the fan 26, the airis effectually circulated just the same, which is of. great advantage in warm weather, as moist cool air isthus supplied without any change in the construction.

The heater element is entirely enclosed and occupies the minimum of space and is properly insulated to revent loss ofiheat, and requires very litt e attention from the at tendant.

By using an electric heater the objectionable features of ashes dust and smoke are obviated. I

The improved apparatus may be constructed of any suitable material and of any suit able size to correspond to the size of the room with which it is associated.

The preferred embodiment of the invention is disclosed in the drawingsand set the specifications, but it will be understood that modifications within the means? struction without departing from the principle of the invention or sacrlficing any of 2 its advanta es.

. Having t us described the invention, what is claimed as new is e 1. In a heating apparatus, a tank for Water, an air intake extending from said tank and communicatin'gwith a room, a shell spaced from the tank and communicating withthe 'room,-Ia heating medium disposed within the shell, andconductor means providing communication between the tank above the Water therein and the shell below the heating medium therein.

2. In a heating apparatus, a tank for water, an air intake extending from" said tank and communicating with a roonf, a shell spaced from the tank and communicating with the room, a heatmg medium disposed within the shell,- conductor means-providing communication between the tank above the water therein and the shell below the'heating medium therein and means for inducing air currents through the shell.

In testimony'whereof, I afiix my signature hereto.
